Dark Crystal Opal Sterling Silver Ring

This has the most amazing opal! It has flashes of green and blue and even purple! It is small, but has some powerful color pops. It is set in a delicate branch style setting. I tend to layer this with other rings. I purchased from a local artist. I am only selling because I am saving up for another ring I want. Even though this is set in silver, this opal is expensive! I have seen other ones, similar size, sell for $800!
